In the Black-Scholes option price model Brownian motion and the underlying Normal distribution play a fundamental role. Empirical evidence however shows that the normal distribution is a very poor model to fit real-life data. In order to achieve a better fit we replace the Brownian motion by a special Lévy process: the Meixner process. We show that the underlying Meixner distribution allows an ...

FUNDAMENT: Psoriasis is a chronic inflammatory systemic disease mediated by immune factors. We will explore the foods that act on these factors contributing to psoriasis. As a systemic disease, which shares the same pathophysiological substrate with other comorbidities, diet also leads to worsening of comorbidities. OBJECTIVE: To indicate a group of foods that can act as a factor of manifestati...

When stopping production, the manufacturer has to decide on the lot size in the final production run to cover spare part demand during the end-of-life phase. This decision can be supported by forecasting how much demand is expected in the future. Forecasts can be obtained from the installed base of the product, that is, the number of products still in use. Consumer decisions on whether or not t...

OBJECTIVES We examined the prevalence of psychiatric disorders among Black Caribbean immigrant ("Caribbean Black") and African American populations and the correlates of psychiatric disorders among the Caribbean Black population. METHODS We conducted descriptive and age-adjusted analyses of the data from the National Survey of American Life--an in-person household mental health survey of noni...

OBJECTIVE This report, following publication of the national life tables (1,2) for 1999-2001, presents state-specific life tables for the 50 states and District of Columbia by race (white and black) and sex. These tables are the most recent in a series of decennial life tables for the United States. METHODS Data used to prepare these state-specific life tables include population counts by age...

Four Black South Africans presented with cardiac failure which was diagnosed as being due to cardiomyopathy. Necropsy examination revealed that all 4 patients had had severe coronary atheroma and myocardial infarction during life.

A number of studies have demonstrated wide disparities in health among racial/ethnic groups and by gender, yet few have examined how race/ethnicity and gender intersect or combine to affect the health of older adults. The tendency of prior research to treat race/ethnicity and gender separately has potentially obscured important differences in how health is produced and maintained, undermining e...

BACKGROUND Deprivation-specific life tables have been in use for some time, but health outcomes are also known to vary by ethnicity over and above deprivation. The mortality experiences of ethnic groups are little studied in the UK, however, because ethnicity is not captured on death certificates. METHODS Population data for all Output Areas (OAs) in England and Wales were stratified by age-g...

In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
